Title: Digital image processor for color image compression
Inventor: FEIG EPHRAIM
IPC: G06T9/00
Filed: 1993-04-21
Abstract: ABSTRACT OF THE DISCLOSURE   This invention minimizes the number of non-trivial multiplications in the DCT process by rearranging the DCT process such that non-trivial multi-plications are combined in a single process step.  In particular, the DCT equations for the row-column application of the DCT process on k=pq points wherein p and q are relatively prime, are factored into permutation matrix, a tensor product between matrices having pxp and qxq points, and a matrix whose product with an arbitrary vector having pq points requires pq - p - q + 1 additions and/or subtractions. The tensor product is then further factored to remove non-trivial multiplications by developing a a first factor having (pq - p - q + 1)/2 non-trivial multiplications and a diagonal matrix. The diagonal matrix is not unique or any set of data. Its jj-th ele-ments are chosen from a subproduct of the factorization of the tensor pro-duct. Once the diagonal matrix elements are chosen the remaining first factor is developed. When the factorization is complete, the diagonal matrix is absorbed into the quantization step which follows the DCT process. The quantization step is the multiplication of a diagonal matrix by the DCT output data. The quantization diagonal matrix is combined with the diag-onal matrix of the DCT to form one multiplication process by which non-trivial element multiply data. This combination of multiplication steps reduces the number on non-trivial multiplications in the DCT process. In addition, the same factorization technique is applicable to the two dimen-sional direct application of the DCT to an kxk matrix of points. Specifically, the transform matrix on kxk points is defined to be the tensor product of the transform matrix on k points with the transform matrix on k points. This results in the individual factors of the transform matrix on k points forming a tensor product with themselves and demonstrates that the fac-torization on k points also reduces the number o non-trivial multiplications on the transform matrix on kxk points. In addition, and similarly, the same factorization technique is applicable to to the application of the inverse DCT on k points and to the inverse two dimensional DCT on a k x k matrix of points. Specifically, the inverse transforms are obtained by transposition of the factorization of the forward transforms, because the DCT is an or-thogonal operator and hence its inverse equals its transpose. Alternately, the inverse transforms are obtained by direct inversion of the individual factors in the factorization of the forward transform.

Title: Method and apparatus for recovering multicomponent vapor mixtures
Inventor: MISSIMER DALE J
IPC: B01D8/00
Filed: 1993-08-13
Abstract: A vapor recovery apparatus which withdraws multicomponent vapor mixtures from processing apparatus (such as gas sterilizers) by condensation at two or more progressively colder levels while maintaining an appropriate balance between components during steps of capture and phase change. Two cold traps provide progressive partial condensation at multiple temperature levels and serve to reduce input energy requirements at least 50% compared to a single cold level. The components in the recovered mixture may include (a) recyclable ozone depleting, global warming and valuable CFCs or HCFCs, (b) hazardous materials and (c) contaminants such as water vapor and air. The system maintains safe balance of component materials by immediately and constantly draining the condensate from a warmer temperature stage into the liquid holding section of a colder trapping zone. The system separates vestigial air or air used as a carrier gas from the condensed mixture and purges it without an unacceptable release or recyclable materials and also it controls water vapor so that frost or ice can not impair performance. After the cryocondensation procedure, valves isolate the system from the processing apparatus, and the system warms the captured condensate to above room temperature. Warming the condensate pressurizes it for transfer to a vessel used for shipping the captured mixtures for reclaiming and reuse. Opening a drain valve in the second cold trap allows captured condensate to flow from the now higher pressure recovery system to the transport vessel without any mechanical pump. The only mechanical device employed for fluid transfer is a small vacuum pump for evacuation of air stripped of condensible materials.

Abstract: ABSTRACT OF THE DISCLOSURE    The present invention legalizes a video signal (e.g., 4:2:2 format) being processed in one format so that the video signal can be transformed to other formats (e.g., analog composite NTSC format).  An editor can be notified of color legalities in a video signal.  Further, each pixel of a video signal can be corrected to the nearest legal value by applying soft limits and gain slopes to a constant luminance color correction process (218) .  In accordance with the present invention, illegal colors of a video signal can be highlighted (238) to provide an output drive (244) for a video display which can be easily monitored by an editor. Alternate features of the present invention relate to error detecting and monitoring (214) by assigning a specific, unique address to each video frame of a video signal.  A further feature of the present invention relates to use of a pixel selecting means (252) which receives 4:2:2 video data in either serial or parallel form.  The data is converted to an analog component format and used to drive a video display monitor where the video image is displayed. The pixel selecting means can, for example, include a mouse/trackball input (256) which is correlated to the video display monitor.

Title: Acceleration Detector
Inventor: NOHARA KAZUYA
IPC: G01P15/18
Filed: 1994-05-19
Abstract: In an acceleration detector fox detecting three-dimensional components of acceleration applied thereto independently with respect to three axes X, Y and Z of an orthogonal coordinate system, a plurality of resistance elements having a piezo resistance effect are formed in a thin-sheet resilient member with an unique arrangement thereof fox improving the sensitivity of the detector. Electric resistance of the resistance elements is varied in response to strain of the resistance elements accompanied with an elastic deformation of the resilient member. The resilient member is fixed at its periphery on a frame of the detector. A weight is connected with a center portion of the resilient member such that the elastic deformation is caused when the weight is displaced by receiving acceleration. When the X- and Y-axes is defined on the resilient member, all of resistance elements for detecting the components of acceleration with respect to the X- and Y-axes are limited within an inner area adjacent to a circumference of the center portion. The inner area is capable of causing a larger elastic deformation than an outer area adjacent to the frame when the weight is displaced by receiving the acceleration. Therefore, an improved sensitivity of the detector is accomplished by the arrangement of the resistance elements.
